Filed: 1990-12-06
Abstract: Selon un procédé de fabrication de fils semiconducteurs quantiques, on utilise une plaquette semiconductrice (14) comme matériau de départ. La plaquette (14) est une plaquette de type p faiblement dopée qui contient une couche p peu profonde fortement dopée afin d'assurer l'uniformité du flux de courant. La plaquette (14) est anodisée dans 20 % d'acide hydrofluorique aqueux afin de produire une couche de 5 microns d'épaisseur ayant une porosité égale à 70 % et une bonne cristallinité. La couche est gravée par la suite dans de l'acide hydrofluorique concentré, qui permet d'obtenir une gravure lente. La gravure augmente la porosité jusqu'à un niveau de l'ordre de 80 % ou davantage. A ce niveau, les pores se chevauchent et on s'attend à voir des fils quantiques se former ayant des diamètres inférieurs ou égaux à 3 nm. La couche gravée présente une émission photoluminescente à des énergies photoniques bien supérieures à la largeur de bande interdite du silicium (1,1 eV), s'étendant dans la zone rouge (1,6 - 2,0 eV) du spectre visible.

Abstract: Présentation d'une méthode et d'un dispositif permettant d'éliminer l'eau accumulée à la cathode (22) d'une pile à combustible électrochimique comprenant une membrane (12) d'échange d'ions en polymère plein. L'eau sous forme liquide accumulée à la cathode peut être éliminée en maintenant une pression partielle de vapeur d'eau dans l'alimentation en gaz renfermant de l'hydrogène à un niveau inférieur à la pression de saturation de la vapeur d'eau pour que l'eau accumulée à la cathode soit attirée par un gradient de concentration vers l'anode (20) à travers la membrane et absorbée sous forme de vapeur d'eau dans l'alimentation en gaz renfermant de l'hydrogène entre l'entrée et la sortie. Dans une application, la pression partielle de vapeur d'eau dans l'alimentation en gaz renfermant de l'hydrogène est maintenue sous la pression de saturation de la vapeur d'eau en lui faisant subir une baisse de pression entre l'entrée et la sortie qui suffit à attirer l'eau accumulée dans la cathode vers la cathode. Dans une autre application, la pression partielle de la vapeur d'eau à l'entrée de l'alimentation en gaz renfermant de l'hydrogène est maintenue en deça de la pression de saturation de la vapeur d'eau. L'eau sous forme liquide qui s'est accumulée à la cathode peut aussi être éliminée en maintenant une pression partielle de vapeur d'eau dans l'alimentation en gaz renfermant de l'oxygène, qui est inférieure à la pression de saturation de la vapeur d'eau pour que l'eau accumulée à la cathode soit attirée par un gradient de concentration et absorbée sous forme de vapeur d'eau dans l'alimentation en gaz renfermant de l'hydrogène entre l'entrée et la sortie. L'eau, sous forme liquide, accumulée à la cathode peut également être éliminée par absorption de la vapeur d'eau tant dans le gaz d'alimentation renfermant de l'hydrogène que dans le gaz d'alimentation renfermant de l'oxygène.
